Naval engineering standard 713 toxic index analysis chamber, Toxicity Index Test Chamber, NES 713
This tester measures the Toxicity Index by ppm in Neval Engineering Standard chamber when complete combustion occurs by burner.
FESTEC's NES 713 TOXIC Chamber meets the standard of NES 713 and is used to measure combustion characteristics about materials.
NES 713 Toxic Chamber measures Toxicity Index after perfect combustion by burning 100g of specimen.
• NES 713: Determination Of The Toxicity Index Of The Products Of Combustion From Small Specimens Of Materials
Control Unit
• Extraction Timer, Stirrer On/Off Timer, Igniter On/Off Timer
• Gas Sol Timer, Air Sol Timer, Process Timer
• Flame Temperature Timer
Utilities
• Methane Gas & Cylinder, 2 Stage Regulator
• Observation window made in reinforced plastic allows easy observation of combustion conditions during the test.
• Chemical reaction with gaseous materials generated in combustion is minimized by treating the inside of Chamber with Teflon Coating.
• Door locking device designed for easy opening/closing
• Specimen Support for Burner to be located in the center of the combustion mass and for test specimen to be easily loaded
• Designed for testing in Auto/Manual Mode
• Auto Ignition for controlling ignition and extinguishment of Gas Burner by Time Device
• Auto Vent Mode allowing auto release of combustion gases generated in combustion by Time Device
• Auto Stirrer Mode for complying with conditions of combustion gas stirrer by Time Device specified in the standard Time Device
If 100g of material is burned and the material is diluted in the air of chamber, concentration of each generated gas is given by the following equation.
C × 100 ×V
C8 = --------------- (ppm)
m
C = concentration of gas in test chamber (ppm)
m = fire test mass (g)
V = volume of test chamber (m3)
Toxicity Index
C81 C82 C83 C8n
Toxicity Index = Σ ------ + ------ + ------ + … + ------
Cf1 Cf2 Cf3 Cfn
1, 2, 3, ... indicates each found Gas.
Cf = concentration of the gas considered fatal to man for a 30 minute exposure time(ppm)
